Application filed Hareh 25, 1910. Serial No. 551,526.

To all whom it may concern:

Be it known that I, SIEGMUND Br er-mama, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in BOXQS Of which the following isa specification.

My invention relates to improvements in boxes formed from sheets ofpaper-box board, or other suitable material, involvin in theirmanufacture the making of a bla'ni t of a desired form and bending suchblank along folding lines to produce the box; and more particularlywhich their corner-portions are reinforced by sections of thecorner-extensions, over- 1 ing the extensions carrying them and lyingatwise against the ad acent walls'ofthe box, as exemplified in UnitedStates Letters Patent Number 931,373, granted to me on August 17, 1909,for improvement in boxes, the resent invention being in the nature of animprovement upon the construction 0' box forming the subject. of thispatent. It has been found in practice that under some conditions theinterlocking lips or tongues on the corner-reinforcements, which-whenthe box is erected are embraced between the end-walls ofthe box and theadjacent. sections of the corner-extensions and which are provided tohold the reinforcements in position on the interior of the box, areliable to become accidentally withdrawn from such position while the boxis in use.

One of my objects is to so construct the box that without the use ofpaste, or any fastener-device, the interlocking tongues or lips of boxesof the variety"herembefore re ferred to, may be positively maintained inposition for holding the corner-reinforcer ments in the positiondesired.

Another object is to provide n ovel means for fastening thecorner-extensions in place with relation to the adjacent walls of the.box in boxes of the type ,involving the reinforced corner-constructionof the patent hereinbefore referred to; and still other objects are toso improve boxes of this type as to augment their usefulness.

Referring to the accompanying drawings, in which five embodiments of myinvention are illustrated, .Figure 1 is a perspective view of a foldablepaper-board boxof the suit-box type illustrating a construction thereofembodying the preferred form of my invention. Fig. 2 is a view of oneend of the to the class of boxes in respectively, showing the manner inthe walls of the box may be erected. F 1g. 24

box shown in Fig. 1, the box in this view being illustrated in lcollapsed condition.

Fig. 3 is a perspective view of one of the four similar corner-portionsof the box of Fig. 1, showing its walls unfolded and the portion of thecorner-extension forming the reinforcement for one corner folded intopositlon preparatory to erectin the boxwalls. F1 4 is a similar view slowing the wall carrymg the reinforcement folded at a right-angle to thebase, this position of the parts of the box being that which they mayoccupy during the righting of the box. Fig. 5 is a view like Fig. 3 ofboth walls erected and the corner-extension and reinforcement thereforfolded into position. Fig. 6 is a plan view of one of the four similarcorner ortions of the blank from which the box illustrated in Fig. 1 isconstructed. Fig. 7 is a perspective view of one of the two oppositecnd-portions of a rectangular box of the hat-box type illustratinganother embodiment of my invention. Figs. 8 to 12 inclusive are viewssimilar to Figs. 2 to 6 inclusive, respectively, of a corner-portion ofthe box shown in *ig. 7 and a corner of the blank from which it isformed, showing the manner in which the walls of the box formed from theblank shown in Fig. 12 may be erected to form the box bf Fig. 7.

Fig. 13 is a View like that. of Fig. 12 showing Fig. 20 is a similarview of one. end of this box showing it in collapsed condition. Figs.21, 22'and 23 are views like Figs. 3, 4 and 5, which is a plan view ofone of the four similar corner-portions of the blank from which the boxof Fig.19 is formed. Fig. 25 is a view of one corner-portion of the boxof Fig. 19 showing the latter in a desired condition for shipment. inknock-down condition; and Fig. 26, a view like Fig. 5 of a modificationof the construction illustrated therein.

still another embodiment of my invention. I

The type of box inronnection with which I have chosen to illustrate myinvention is of the collapsible variety involving, generally stated, a'base having four walls hingedly connected with the base, withextensions carried on the ends of opposed walls adapted to be foldedflatwise against the adjacent walls of the box and held in positionagainst accidental displacement by flaps carried by the walls againstwhich the extensions are folded. 7

Referring to Figs. 1 to 6 inclusive, the box in'its erected condition isrepresented at 35. The blank 36 from which this box is formed consistsof an oblong rectangular sheet of boX-board-, or the like material,provided with parallel folding lines 37 (one only of which is shown)along which the blank is foldable on the base 38 to form the sidewalls39 of the box, and parallel folding lines 40 disposed at right-angles tothe lines 37 along which the blank is foldable to form the fourcorner-extensions 41 and the end-walls 42 of the box, this feature ofthe construction being the same as that disclosed in the above-referredto patent. As each of the four corner-extensions 41 of the box is of thesame construction and is formed in the same manner, but one of suchextensions is described in detail as follows: Each corner-extension 41is formed of two sections 43 and 44 hingedly connected with the ends ofthe adjacent walls along the folded lines 45 and 46 and with each otheralong a diagonal folding line 47; and a third section 48 which issevered from the section 44 along a line 49 extending parallel with theline 46 and a line 50 which latter is atan angle to the line 49, thesection being hinged to the sections 43 and 44 along the line 51 andbeing provided at its outer end with a folding line 52. The section 41is slit along the line 53 paralleling the line 51 and along anale-shaped line 54, a diagonal folding line being provided in thesection 48 extending from the inner end of, the line 53 to its juncturewith the folding line 52. The line 49 is located between the outer edgeof the section 48 and the folding line 4 so thata tab 56 is formedon'the section 44 and has hinged connection with the end wall 49 alongthe line 46. By

partially severing the section 48 from the sections 43 and 44 andcutting the section 48 along the lines 53 and 54, this section isconnected with the sections 43 and 44 through the medium of twotongue-like members 57 and 58. The foldable sections of the extensions41 are so formed that when the sections 48 are folded along the line 51to the position illustrated in Fig.

' 4, they will overlie the adjacentends of the walls 39 carrying them,the lines 52 registering with the adjacent folding lines 45. When thebox is erected the sections 48 will fit into the corners of the box; thelines 55 registering with the lines 47. The end-portions of the blankintermediate the sections 41 are adapted to be folded inwardly anddownwardly along dotted folding lines 57 (one only of which is repre,sented) to forrn'end-flaps 58" for a purpose hereinafterexplained, theseend-flaps being provided at---'=itl te ir ends with tongues 59 formed byslitting the flaps longitudinally illustrated in Fig. 4, .whereupon theend- Y walls 42 of the box are righted and the extensions 41 folded uponthe lines 45, 46 and 47 and the diagonal lines 55, to cause theextensions 41 to extend inwardly and.. lie against the inner faces ofthe adjacent end-walls 42 of the box, the inner ends of the members 58to lie between the sections 44 and the inner surfaces of these end-walls, and the outer ends of the sections 48 to lie against theside-walls, all as. represented in Fig. 5 of the parts forming thebox-corner therein illustrated. The flaps 58 may then be folded inwardlyalong the. foldinglines 57 to overlap the extensions 41 for holding thelatter in place, in which position these flaps in the constructionillustrated are designed to be held in 'place by flexing the tongues 59and introducing them between the adjacent extension-sections 43 and 48into the "pockets which are provided by forming the box as described,the position'these-tongues assume in the locking operation being thatillustrated in Fig. 1. The box may be collapsed by withdrawing thetongues 59 from looking engagement with the sections 48 and thenpressing the endwalls 42 outward and the side-walls 39 inward, to causethem to assume the position illustrated in Fig. 2, from which conditionthe box may be again readily righted by turning the end and side-wallsat their hinged. connections with the base to upright position, therebycausing the extensions to fold along the lines 45. 46 and 47 to theposition illustrated in Fig. 5 and then fastening the flaps 58 inposition as described; or the box may be collapsed to a position inwhich each corner thereof occupies the position represented in eitherFigs. 3 .or 6, from which positions the box may be erected ashereinbefore described. It will be noted from the foregoing descriptionthat the tongue-members 58 formed by cutting the sections 48 to formopenings, when the box is set up, for receiving the the tab 56 of thepreceding figures.

tongues 59, are held against accidental withdrawal from their positionof embrace between the sections 44 and the adjacent walls 42 of the boxby reason of their hinged connection with the sections 44, when theextensions 41 and walls 39 and 42 are folded to form the erected box,and thus the reinforcing sections 48 are held in the proper position atall times against the inner surfaces of the box-corners while the box iserected.

The construction illustrated inlFigs. 7 to 12 inclusive is of dimensionsrendering it suitable for use as a hat-box. One of the fourcorner-portions of the rectangular blank from which this constructionmay be formed is represented in Fig. 12. The blank is formed withfolding lines 61 and 62, one only of each of which 1sillustrated,-defining a base 63 and side and end-walls 64 and 65,respectively. The corner-extensions represented at 66 are formed of twosections 67 and 68 hinged to the side and end-walls alongthe foldedlines 69 and 70 and to each other along the diagonal line 71; and athird reinforcing U shaped section 72 hinged along lines 7 3 and 74- tothe sections 67 and 68 through the medium of parallel tongues 75 and 76,the section 72 being partially severed from section 68 along the lines77 to 82,

inclusive, the line 81 being positioned to the left of line 70 in Fig.12 and the line 82 being diagonal to form a tab 83, similarhtio e outerend of each section 72 is formed with a folding line 84 parallel withthe folding lines 73 and 74 and each tongue 76 is formed with a foldingline 85. The end walls 65 carry flaps 86"hinged thereto along lines 87and formed with tongues 88 as described of the flaps 58. The box isformed from the blank in the manner described of that shown in thepreceding figures,-the sections 72 folding back against the sections 67and 68, and the side walls 64- of the box and the line 85 registeringwith the line 71 as illustrated in Fig. 10. When the blank is folded tothe position illustrated in Fig. 11, the endflaps 86 may be folded downover the extensions 66 and the tongues 88 thereupon inserted between thesections 72 and the underlying sections 67 to the position illustratedin Fig. 7. The sections 68, where the box is of dimensions adapting itfor use as a hat-box, are relatively long and where they meet asillustrated in ltig. 7 they may be fastened together-as indicated at 89,as by staples or other fastening means passing through them and thewalls 65, and the pocket thus formed be utilized to receive alongitudinally-extending tongue 90 as represented in Fig. 7 serving asadditional flapfastening means.

In Fig. 13 I. have illustrated a blank which differs slightly from thatillustrated in Fig. 12 as regards the location of the lowersection-connecting tongue. In Fig. 13, this lower tongue which isindicated at 91 is represented as being in alinement at one edge withthe folding line 70. Thus the connections between the tongues 91 thusformed, and the sections 68 is closer to the extremity of the sections72 than in the case of the construction illustrated in Fig. 12, which isof advantage under some conditions.

The construction of box of Figs. 14 to 18, inclusive, is the same asthat of Figs. 7 to 12, inclusive, excepting that in the first referredto construction the blank is so cut, as illustrated, as to form tongues92 on the ends of the flaps 86, which extend longitudinal] of the flaps86 beyond the margins of the ase 63, and similarly extending tongues 93located intermediate the tongues 92 as represented in Figs. 14 and18,-the extremities of the reinforcing sections 72 containing' openin s94 Wl'llCll register with the tongues 92 when the box is erected. Thebox may be erected as described of the ones illustrated in the precedingfigures, the tongues 92 automatically springing into the adjacentopenings 94 when the operation of righting the walls is etfected andresisting any tendency to collapsing of the box by engagement with thewalls of such openings. The additional flapsecuring means just referredto serve tosupplement the locking functions of the tongues 93 and undercertabiln conditions their employment is desira e.

In Figs. 19 to 24, inclusive, is shown still another embodiment of myinvention, these figures illustrating another form of means within myinvention for securing the end-flaps of the box in position. One of thefour similar corner-portions of the blank from which this box is made isrepresented at 95, the blank being of general rectangular form andhaving folding lines 96 and 97, one only of each of which is showndefining the base 98 and side and end-walls 99 and 100, respectively, ofthe box. The corner-extensions of the box are represented at 101 and areformed of two sections .102 and 103 hinged together along the diagonalvfolding line 104 and to the adjacent side and end-walls of the box, asindicated at 105 and 106 respectively; and a third section 107 severedfrom the section 103 along the lines 108 and 109 to form on the sectionis formed into the box of Fig. 19 as described of the precedingconstructions and illustrated in Figs. 21 to 23 inclusive, thecorner-sections bending inwardly upon the lines 104,105, 100 and 113,and the section 107 lying against the sections 102 and 103 and theside-walls of the box as illustrated. After the corner-extensions andwalls are' erected, the flaps 116 are bent over the extensions and thetongues 118'inserted into the slits 114 between the reinforcing sections107 and the sections 102 for holding the flaps '116 in position.

In Fig. 25 I have shown the box of Fig. 19 in collapsed condition, thisView showing the box in a condition in which I prefer to ship it. Inractice, the operator will first turn theendaps 116 down against theinner surface of the end-walls 100 and thereupon fold the extensions 107to the position illustrated in Fig. 22 and then turn them down upon thebase 98 and end-walls to cause the tabs 110 to overlap the .ends of theflaps 116, as illustrated in Fig. '25. The operator will then staple orotherwise fasten the sections 103 and the inner portions of sections 107to the end-walls as indicated at 119. The

flaps 116 are thus held down and are revented from interfering with thedesired ease in handling the collapsed boxes. When it is desired to usethe box the flaps 116 may be readily sprung out of engagement with thetabs 110 owing to their inclined ends, and the end and side-wallserected to form the box by turning the end-walls upwardly and inwardlyand the side-walls upwardly and outwardly.

It will be understood that the blanks of the previously describedconstructions, as well as that of Fig. 19, may be folded to the positionillustrated in Fig. 25. Furthermore, those portions of thecorner-extensions which fit against the ends of the box in each of theconstructions illustrated may be secured in position against such wallsas indicated, by staples or in any other -suitable manner, where it isdesired that the box be shipped in collapsed condition. Such securingmay take place, if desired, at the tabs represented at 200 which extendtoward the center of the end-walls in each construc-' tion beyond theline at which the sections of the corner-extensions fold on each otherin righting the box.

It wi'll be manifest from the foregoing description and the drawingsthat the reinforcing corner-sections are joined" to the other twosections of the cornerextensions through the medium of tongue-membersinticularly where such tongues are on flaps on such walls is of valuelll'bOX constructions, as it affords economical and effective means forholding the box erected, as the pockets becoming acciv for engaging withthese tongues are formed in the act of stamping the blank.

While boxes employing retaining flaps on opposed walls, secured theretoin any suitable manner, are of the type to which I prefer to apply myinvention, it is readily apparent that such invention, in so far as thefeature of holding the reinforcing sections in place are concerned, willhave utility in constructions corresponding to those illustrated withthe end-flaps omitted. Such omission would, however, require theapplication to. the extensions, after they and the walls had beenrighted and the box placed in non-collapsed condition, of means (notshown) for fastening the extensions to the walls against which theywould lie and these means might be of any suitable form.

While I have illustrated certain forms of constructions in which myinvention may be employed, I do not wish to be understood as intendingto limit my invention to its embodiment in these particular forms, asvarious modifications of the ,constructions shown and described may bemade without.

departin from the spirit of my invention.

The ti the end-flaps in place by leaving such tabs free instead offastening them. to the endwalls, in which case the insertible tongues onthe end-flaps should be cut off, thereby permitting the flapsintermediate their ends to be inserted under the tabs 200, Fig. 26,

the tabs provided being useful either as means for securin thecorner-extensions against the box-en s by fastening the tabs s 200 maybe utilized for locking to the latter, or as means for lockingthe box inset-up condition by; leaving them free. Where ,the tabs 200 cooperatewith the endflaps for locking the box in set-up condition it ispreferred that such end-flaps be formed with a longitudinally-extendingfolding line (not'shown) as well understood in the art for facilitatingthe operation of inserting the flaps under the tabs.
